According to the utility model, the precision and the yield rate of the material feeding are improved through flatly jointing the high polymer with the substrate.

Description

Metal form

Technical field

The utility model is about a kind of metal form, particularly relevant a kind of metal form with polymeric membrane.

Background technology

As shown in Figure 1, it is to comprise housing 1, be adhered to the supporting network 2 of housing 1 and be arranged at the metal forming plate 3 of the perforate 6 of supporting network 2 that existing solder ball is put metal form, and metal forming plate 3 has a plurality ofly puts the figure of soldered ball and the feedholes 4 arranged with desire.

As shown in Figure 2, it during the metal form operation substrate 5 that metal forming plate 3 is attached at operation, a side opposite with substrate then sent into soldered ball, fall to substrate 5 via feedhole 4 again, so that on substrate 5, form predetermined figure, as shown in Figure 3A, when soldered ball 7 drops down onto fixed point on the substrate 5 via feedhole 4 after, side at feedhole 4 close substrates 5 must have certain distance with substrate 5, make soldered ball 7 after metal form is taken away, can be attached on the substrate 5 smoothly, therefore, the one side that contacts with substrate 5 at metal forming plate 3 needs have with feedhole 4 drop of certain altitude, existing metal forming plate 3 is that the mode with etching or electroforming forms this height, as shown in Figure 3A, be with near the height fall 8 of the metal attack the perforate with etching mode with formation feedhole 4 and contact-making surface, this etching mode can cause plate surface evenness deficiency, can't amass with substrate or the full sheet of operation wafer and fit tightly, can cause soldered ball to put fraction defective increases, shown in Fig. 3 B, be on the contact-making surface of metal forming plate 3 and substrate 5, to form a considerable amount of tiny metal mainstays 9 with electrocasting, come scaling powder on isolated and the substrate, the contact of electronic component or electrode, yet too high easy damage electronic component of metal mainstay 9 hardness or electrode, and the height of metal mainstay 9 differs, also can't amass and fit tightly with substrate or the full sheet of operation wafer, moreover metal mainstay 9 ruptures because of collision or wiping when metal forming plate 3 carries out cleaning operation easily.

The specific embodiment

Fig. 4 is the stereogram that shows the utility model metal form, and Fig. 5 is the stereogram that shows the utility model metal form, and as shown in the figure, metal form 10 of the present utility model comprises a housing 11, is metal material, is made by materials such as iron or aluminium; One has a perforate 120, one first is provided with the supporting network 12 that face 121 and one second is provided with face 122, described supporting network 12 is provided with face 121 by first and is arranged at described housing 11, described supporting network 12 can be made by fibers material or metal material, is fixed in described housing 11 by bonding or welding manner; And the metal forming plate 13 with a metal forming body 130 and at least one polymeric membrane 131, described metal forming body 130 has a plurality of feedholes of arranging in set mode 132, arrangement mode is to put the operation thing figure of soldered ball and decide according to desire, described polymeric membrane 131 and the described feedhole 132 both set a distance and coat described metal forming body 130 of being separated by, described metal forming plate 130 corresponding described perforates 120 are connected with described supporting network 12, and described polymeric membrane 131 is provided with 122 homonymies with described second.

Fig. 6 is that top view is amplified in the part that shows Fig. 4; As shown in the figure, polymeric membrane 131 is coated described metal forming body 130 and apart from feedhole 132 arrange regionals one set distance X, that is, polymeric membrane 131 on the cloth all in zone that no feedhole 132 on the metal forming body 130 is arranged.

Fig. 7 is the local enlarged side view when showing metal form operation of the present utility model, as shown in the figure, during metal form 10 operations the substrates 20 that metal forming plate 13 are attached at operation by polymeric membrane 131, a side opposite with substrate 20 then sent into soldered ball, fall to substrate 20 via feedhole 132 again, so that on substrate 20, form predetermined figure, when soldered ball 30 drops down onto fixed point on the substrate 20 via feedhole 132 after, at a side of feedhole 132 close substrates 20 and the thickness H of the described polymeric membrane 131 of substrate 20 distances, soldered ball 30 can be attached on the substrate 20 after metal form 10 is taken away smoothly, and can prevent that soldered ball 30 positions from putting and move to other electrode zones to the location and cause short circuit.

As mentioned above, the high strength that metal form 10 of the present utility model is made metal forming body 130 and contact-making surface coating one deck macromolecular material of substrate 20, high density, high fineness, high resistance, the polymeric membrane 131 of high-flatness, therefore, polymeric membrane 131 can very smoothly fit tightly in substrate 20, the minimizing element damage that facility pressure causes during because of operation, in addition, polymeric membrane 131 support forces of large tracts of land coating are big, stability is high, anti-mechanicalness is strong, and but single or multiple lift lays, to improve anti-chemistry and can adjust thickness easily, so metal form of the present utility model 10 can improve scolder storing rate and precision, and fully reduce electrical condition of poor, and then reach and improve metal form service life, improve the purpose of operating accuracy and yield.
